Warhorse Studios' gritty medieval RPG Kingdom Come: Deliverance has sold around 500,000 copies in just two days.
Game designer Daniel Vavra broke the news on CzechTV (as reported in Czech newspaper Hospodarske Noviny), revealing the title was on track to break half a million sales at some point today.
The game launched to a mixed reception on February 13, with bugs and performance issues marring what's otherwise been praised as a detail-rich, engrossing experience.
It's also Steam's top selling title at the time of writing, and boasts an all-time concurrent player count of over 75,000 players.
